i j GUN-SIGHT 1'0 all whom it may concern:

7 zen' of the United States, residing at Geneva, p in the countyv of Ontario and State of New *1 ,1 5 York, have invented certain new and useful improvements in Gun-Sights, of which the following is a specification. v

' My invention relates toguu-sights; and the 'f .10 thesight proper and'in means for adjusting ;the same, ashercinafter more fully described.

--Figurel is aperspective viewof my imroved'sight attached to av gun. 'Fig. 2 is a T 15.} end and one at the center mid way of its length.

These disks are made of considerable thick.

'ness and of 1 such a diameter as -to fit snugly in the bore of the tube, they being simply shoved or forced into place. disks isprovided at its center with a small hole, about the size of those used in the-0rdi-- x Hfnary peep-sights, the three holes being ex- 7! assshown, is reamed out aroundthe hole on 1, i each side, care being taken to have the sura j face ofthe conical recess thus formed-stand Fat an. angle of fortyfive degrees, orpractically $0. Theinnerfacesof-thetwoenddisks aand c are in likeman'ner beveled at the 0 same angle, while their outer faces are made concave on the arc of acircle, as, shown in Fig. 3. I would here remark thaflgobd'i-esults may be produced bymak'ing the outer v faces of these end disks beveled similar to gt-heir. inner faces, but not so perfect asby making them circularly concave, and that while both forms come within thescope of my invention I prefer the form described as givng the best results.

For convenienceof attachmcntlreducethe xternal diameter of the tube A for a little minimums 111111 21, 1890. send in. 848,739, moi ten reduced portionanother v this latter being provided at=itsrear end with j Y Be it known' that LCHARLES Burton, 9. citi-' i an enlarged concave disk of the usual form invention consists 'in a novel. construction of rearface view, and Fig. 3 is a side elevation.

se e ate m1)- As shown in Fig. 3, thegparts Aand A are provided with screw-threads,withaspace left between their abutting shouldera'so that by screwing upthe partA. their shoulders are made to clamptheslidc Dand the leaf B, as. V

shown,ther e preferably being a collar 0 arranged to bear against the rear face of the leaf B, as shown in Figs. Land 3, though this is not absolutely essential. The result of this 6 5 a construction is that all-therays of light in front of' thesight are prevented from reach? ing the eye, except those which proceed in a straight line from the target or object to and [through the holes in the three disks. All

other rays of light which enter the hole in the disk 0.; coming as they must at an angle more or'less, will strike the inner wall orsurface of the tube A and be reflected at a corresponding angle to the "opposite wall, as indicated by the lines in Fig. 3, and will thus be pre-' vented from passing through the hole in'the' central disk' I). the tube A' is also blackened, in'orderto absorb'. the rays of light which impinge upon'it,

and thus prevent their reflection, the same as in telescopes.

The inner wall or surface of When an object is viewed through thissight;

only a very small field around theobjectcan be seen, and the object or target stands out clear and well defined .with a remarkable sharpness of outline. The field of sight being so limited, the slightest movement of the gun is instantly perceived by the person holding it, and this aids to secure greater accuracy. r

This sight is designed to be used incbnnec tionwith a front sight, preferably of the. kind known-as globe sights. 'Itmaybemounted. i

in any manner desired; but for convenience of support and to enable it to be adjusted with accuracy, and at the same time be capable of being thrown over to one side'when it is .desired to wipe out the gun-barrel'and return the sight to its exact former position,'I mount it in the manner shown in the drawings, in

whichP'represents th'e base-plateflqtrwhich is hinged,- by the screw g, a shortleafa Llarranged to swing to and iiro in line 'wi th the. E

barrel of the gun. To this short leaf'I, I Ipivotanotherleaf B by means of, a. screwh, so that this leaf B can be turned over laterally, as indicated in Fig its lateral mowe- 5 'ment'being carried to' any extent desired.

, The leaf B-is provided on its rear side with a '15 and thus change .the inclination of the sight A, its front end being lowered by throwing the leaf forward and raised by throwing it backward. 0n the plate-P, at the side of the lug E, I make a projection R, as shown in the :0 several figures, and in the side of this projection next to the lug, I inset a screw f, as shown in Figs. 1 and 3, against which the side of the lug bears when the, leaf B is turned upto the vertical position. This screw serves as a windgage, for by turning the screw f in or out the leaf with the sight can be adjusted to the right or left to any extent desired, and thus compensate for the elfect of the wind on the bullet during its flight, whether the wind he go fromone or the other side. 'I prefer tomake this lug Ein the form of a plate,- as shown, *asby-t-hatmeans I secure a-good bearing on ,both the front and rear faces of the leaf I, as

shown-clearlyin'Fig. 2, andthus'insure firm- .ness of position and accuracy of movement. It is obvious that by turning the leaf B'the other side foremost the part which bears against the leaf I could be extended down to forn the lug or that leaf B and lug E may be 0 madeintegral by milling out the space for leaf 1; but I prefer the plan shown, as the parts canbe fitted with great accuracy, and,

-moreover, the wear can be compensated for by tightening the partsb'y mean's'of the screw- 5 pivot hi The sight'is secured to a slide D, which is moved verticallyin the slot of leaf B by a screw 0, as shown, these being well known. The reduced portion of tube A is put through a hole in the slide, and then the collar 0 is slipped on and the sleeve A screwed on, thereby clamping it fast to both the slide and the leaf, thus preventing the slide from being moved until the sleeve is slightly loosened, when-the slide with the sight can be raised or lowered, as desired, after which the sleeve ifs screwed up again, thereby locking the parts ast. By this construction I am enabled to produce a sight peculiarly adapted for fine targetshooting and that can be adjusted-with great accuracy, .b oth vertically and laterally, that can be made to serve as a wind-gage, thereby avoiding the necessity of adjusting the front sight when once properly set, and that enables the sight to be turned-outJ-Of the way when it is desired to clean the barrel, and to bring it back to the exact position from which 'it was moved.

. Having thus described my invention, what I claim is- I 1. A sight for guns, composed of a tube having two or more perforated disks arranged 'therei'n, substantially as shown and described.

2. In combination with a tube A, a central perforated disk havin its faces beveled at an angle of forty-five degrees on its opposite sides and two end disks also perforated and having their inner faces beveled at an angle of forty-five degrees and-their outer faces 'made concave on the are of a circle, as set forth.

3. The combination, in a gun-sight, of the base-plate P, the leaf 1, hinged to swing in line with the barrel, and a leaf B, pivoted to the leaf 1. and arranged to swing at right angles to the ,movement of leaf I, substantially as shown and described. p 4. In combination with the base-plate P, a leaf adapted to support a sight and to swing on to and fro in the line of the barrel, and .an

adjusting-screw 1-, all arranged to operate substantially as and forthe purpose set forth.

5. The plate P, provided with a projection R- and screw f, a leaf B,'pivoted to swing lat- 5 erally, and provided with an arm or lug arranged 'to strike againstsaid screw when the leaf is turned up into position, substantially as described.

6. In combination with the slide D and 10:: hinged leaf B, the tubular sight A, provided with the perforated disks a, b, and 1;, arranged to operate substantially as shown and described. In witness whereof I hereunto set 'my hand :0 in the presence of two witnesses. CHARLES BUNGE. Witnesses:
